Analysis and recommendation of HVAC modifications to replace central cooling plant. Five central plant options were evaluated for:

  • First cost
  • Annual energy/utility cost comparison
  • Maintenance and service cost
  • Cumulative 20-year life cycle cost


Other mechanical upgrades:

  • DDC building automation system
  • Fan powered VAV boxes to replace the existing dual duct boxes
  • Sheet metal duct changes to reduce noise and pressure drop improving overall system performance
  • Renovating existing 140,000 CFM air handlers in place with new coils and VFD drives versus replacing systems with new rooftop air handlers and packaged controls
  • 24-hour, 7-day supplemental cooling loop for data closets and computer rooms
  • Team position: prime A/E for study and cost evaluation
